Bonk is a an audio compression program that operates in both lossy and lossless
modes. The compression method Bonk uses is quite simple compared to other lossy
formats (such as MP3), and is based on speech compression techniques. It is
nevertheless capable of producing a high compression ratio while maintaining
good sound quality.
In lossy mode, it averages 14:1 compression while remaining almost perceptually
lossless. This corresponds to 95 kbps for reasonable quality audio.
In lossless mode the original audio file can be recovered exactly. Lossless
mode typically achieves around 2:1 compression.
Bonk compiles under Linux, FreeBSD, NetBSD and OpenBSD. (Note: I personally
only have access to Linux machines. I can't test Bonk on other operating
systems, just apply patches people send me. So if it isn't working on other
systems, please email me!)
